Service Provider Connections

This chapter explains service provider connectivity
and provides information detailing how to configure
different service provider connections for SMS messaging using the
Ozeki NG - SMS Gateway software.

In SMS messaging using Ozeki NG - SMS Gateway, a service
provider is an entity that is responsible for sending and delivering SMS
messages from users/applications of the program to recipient mobile phones,
and responsible for sending SMS messages from mobile phones to Ozeki NG -
SMS Gateway, which will deliver them to users/applications
of the program.

To be able to send and receive SMS messages using Ozeki
NG - SMS Gateway, you need to pay one or more GSM service providers for
the service described above, and you have to connect Ozeki NG - SMS Gateway
to the SMS Center of one or more service providers.

You can do this in two ways:

You can connect directly to the SMS Center of a GSM
service provider over the Internet. In this case, you need to make
a contract with the service provider. In compensation for your subscription,
the GSM service provider will provide you with the information required
for connecting to the SMS Center over the Internet (hostname, port, username,
password).

You can connect to the SMS Center using a GSM modem
attached to the PC with a phone-to-PC data cable. In this case you
pay for the service by buying a SIM card from the service provider.

Direct connection to the SMS Center by setting up an IP
SMS account with one or more GSM service providers has several advantages,
including a greater speed and reliability.

The format of SMS messages exchanged between Ozeki NG - SMS
Gateway and the SMS Center of the GSM service provider is governed by an SMS
protocol. When you install a service provider connection, you have to select
the appropriate protocol. The service provider will tell you which protocol to
use and will give you the protocol-specific parameters, such as the username
and password, IP address etc.

Ozeki NG - SMS Gateway allows the installation and configuration of the
following protocols / service provider connections:
